Peroxisomes are cell organelles that carry out a number of functions, including the degradation of cytotoxins. For this purpose, they require enzymes that have to be transported into peroxisomes via complicated machinery. The team from the research group Biochemistry of Intracellular Transport Mechanisms at Ruhr-Universität Bochum (RUB) headed by Professor Harald Platta has detected an as-yet unknown transport step, thus gaining a better understanding of life-threatening diseases. The group published its report in the renowned journal Biochimica et Biophysica Acta – Molecular Cell Research in February 2019.
